Dual purpose pipe



Oct. 5, 1965 JAMES Y. SHIH DUAL PURPOSE PIPE Filed April 29, 1963 INVENTOR- United States Patent M 3,209,764 DUAL PURPOSE PIPE James Y. Shih, 819 Aldine Ave., Chicago, Ill. Filed Apr. 29, 1963, Ser. No. 276,458 2 Claims. (Cl. 131173) This invention generally relates to smoking pipes and more particularly to liquid filters and the capability of conversion thereof between a filtered and unfiltered pipe.

The main objectives of this invention are to provide a pipe which can function as a liquid filtered pipe or an unfiltered pipe by rotating the stem; to provide a pipe with a liquid filter which can remove most of the condensation and undesired particles from the tobacco smoke; to provide a liquid filtered pipe with a safety valve on the stem to open or close the liquid chamber in one rotation; to provide a liquid filtered pipe with an inclined baffle which can break liquid bubbles and allow the liquid drops to flow back to the liquid chamber along the inclined bafile surface; to provide a liquid filtered pipe with a safety valve on the stem to prevent any leakage of the filtering liquid; to provide a liquid filtered pipe with a safety valve on the stem of the pipe and allow for economical production of this invention.

These, together with other objectives and advantages which will become subsequently apparent, can be seen in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the dual purpose pipe.

FIGURE '7 is the same fragmentary portion of the dual purpose pipe in another position.

The essential concept of this invention involves a smoking pipe with a body upon which a tobacco receiving bowl and a stem are assembled. The stem has a smoke channel communicating therethrough with either the smoke channel of the body leading directly to the tobacco bowl or the liquid filter chamber wherein the tobacco smoke is filtered. The manner of interconnecting the channels, from the tobacco bowl directly to the stem or from the tobacco bowl through the liquid filter chamber then to the stem, depends on the angular position of the stem.

A dual purpose pipe embodying the foregoing concept comprises a body 10, a stem 1 and a tobacco bowl 5 (FIG. 2). The stem provides a smoking tip 19, a smoke channel communicating the smoking tip 19 and the open end 2, on the side wall of the end 3. A valving groove 4 is provided on the stern opposite the open end 2. The body 10 is hollow and generally elliptical, or the like. Inside the body 10 there is provided filtering liquid 15, a tube 16 and a baffle 14. The body 10 includes an upper horizontal wall having a smoke channel 12 communicating with the smoke channel 9 of the tobacco bowl 5 and the valving groove 4 (FIG. 2) on the stem 1 or the smoke channel 2 (FIG. 4) of the stem 1, smoke channel 13 communicating the tube 16 and a pocket or slot 18 3,209,754 Patented Oct. 5, 1965 communicating with the liquid chamber 17 and the smoke channel 2 of the stem 1 (FIG. 2) or in a non-filtering state (FIG. 4). The tobacco bowl is provided with a refractory lining, or inner bowl 6, a plastic outer bowl with fins 7 and an eccentric neck 8.

In the operation of the device, it is necessary to remove the tobacco bowl 5 and fill the chamber 17 with filtering liquid 15, such as water or other flavored liquid if desired, as shown in FIGURE 2. Then the neck of the tobacco bowl 5 is placed in the bowl adapting well 11 and the bowl is filled with tobacco of desired brand. The smoker may place the stem 1 in his or her mouth and commence smoking in the usual manner. The tobacco smoke from the burning tobacco is allowed to travel through the smoke channel 9 of the tobacco bowl 5, the smoke channel 12 of the body 10, the valving groove 4 of the stem 1, the smoke channel 13 of the body 10, the tube 16 and into the filtering liquid 15. The filtered smoke bubbles are crushed by the baffle 14 and continue to travel through the pocket or slot 18, the open end 2 of the stem 1 and to the smoker. The bubbling action of the smoke may leave drops of the filtering liquid on the baffle 14. The inclined surface of the said b-afile guides said liquid drops back to the filtering liquid 15. The baifie shall also prevent the filtering liquid from flowing into the stem open end 2 when the dual purpose pipe is used in an inclined position as shown in FIGURE 6.

Referring to FIGURE 4 and FIGURE 5, the stem has been rotated approximately from its position shown in FIGURE 2 and FIGURE 3. This is the position in which the dual purpose pipe is used as a non-filtering pipe. The tobacco smoke is allowed to travel directly from the smoke channel 9 of the tobacco bowl through the smoke channel 12 to the stern open end 2 and to the smoker. The smoke channel 13 is now obstructed by the stem. The filtering liquid is now sealed inside the chamber 17 and it is the suggested stem position for one to carry the dual purpose pipe in a pocket.

For changing fresh filtering liquid one can remove the tobacco bowl 5, drain the used liquid and refill with a quantity of fresh liquid. The tobacco bowl is kept cool at all times because the fins 7 provide good heat transfer characteristics. The eccentricity of the neck 8 is designed to provide good alignment between the smoke channel 9 and the smoke channel 12. The use of synthetic resin and refractory lining throughout assures low manufacturing cost.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

Having thus completely and fully described the invention, what is now claimed as new is as. follows:

1. A tobacco pipe comprising a body member including means in a lower portion thereof for containing filtering liquid, said body having a horizontal upper wall portion having a Well having a vertical axis, a tobacco bowl having a vertical axis and a stem depending from the lower portion thereof and having a smoke duct therein comprising a first portion leading downwardly from the interior of the bowl to an intermediate portion of the stem, and a second portion leading horizontally from the lower end of the first portion to an exit located at one wall of the stem intermediate the upper and lower ends thereof, said body member having a shoulder adjacent one side portion of the upper Wall and having means for receiving a mouthpiece portion, the upper wall of the body member having a horizontal smoke tube communicating between said well and said mouthpiece receiving means, the well in the body member being eccentrically disposed with respect to the center of said upper wall, and the depending stern being eccentrically disposed with respect to the vertical axis of the bowl whereby when the bowl is positioned on said body with the depending stern in said well, positioning the bowl so that the vertical axis thereof is located at the center of the upper wall will align the horizontal portion of the smoke duct in the depending stem with the horizontal smoke tube in the upper wall so that smoke may be drawn from the bowl through the depending stem, the horizontal tube to and through the mouthpiece.

2. A tobacco pipe as defined in claim 1, where said upper wall has a depending tube and a smoke channel for communicating the upper end of the tube with the horizontal tube in the upper wall adjacent the shoulder, said body having a baflle extending from an upper portion of a side wall thereof and inclined downwardly toward said filtering liquid, the lower end of the depending tube extending into the liquid and being disposed below the baffie, the mouthpiece having a free end portion extending upwardly from the shoulder and having an axial smoke duct therein extending from said free end to the portion of the mouthpiece received in said shoulder, said mouthpiece duct terminating at the lower free end thereof in a portion angularly directed toward an inlet in a wall portion thereof, said lower end portion of the mouthpiece having a groove in the wall portion thereof opposite said inlet whereby the mouthpiece may be positioned so that smoke may be drawn from the bowl through the depending stem, the horizontal tube in the upper wall, through the smoke channel, through the depending tube into the filtering liquid and into the smoke duct in the mouthpiece through the inlet in the wall portion thereof when said mouthpiece is rotated so as to be displaced about said duct from the position wherein smoke is drawn into the mouthpiece directly from the tube in the upper wall.
